Aaron was called and set apart to the priestly office by revelation from God through Moses, and retributive punishment fell upon all who essayed to minister without authority in the priest's office. Consider the awful fate of Korah and his associates (Num. 16), the instance of Uzziah king of Judah (2 Chron. 26), and, in New Testament times, that of Sceva's sons (Acts 19), all of whom brought upon themselves condign penalty for blasphemously arrogating the right to officiate in the name of the Lord. How great a lesson is writ for warning and guidance in the history of Saul, king of Israel. He had received his anointing under the hand of Samuel the prophet. On the eve of battle, when Samuel delayed his coming to offer sacrifices for victory, Saul presumptuously officiated at the altar, failing to realize that, king though he was, his royal authority did not empower him to serve even as a deacon in the household of God. His sacrilege was one of the principal causes that led to his rejection by the Lord. While in the flesh Christ chose His Apostles and ordained them, bestowing upon them specific authority. Those who were afterward called through revelation, e. g., Matthias, Saul of Tarsus who came to be known as Paul the Apostle, Barnabas, and others, were ordained by those previously invested with the Holy Priesthood. Elders, priests, bishops, teachers and deacons in the Primitive Church on the Eastern hemisphere were all similarly ordained; and so a succession was maintained until the Church, corrupted and apostate, was no longer worthy to be called the Church of Jesus Christ, because it was not; and the real Church, characterized by investiture of the Holy Priesthood, was lost to mankind. When the Resurrected Lord established His Church on the Western Continent, He called and personally commissioned Twelve Disciples; and later, others were with equal definiteness and certainty called and ordained to priestly functions by revelation through those in authority; and this order continued in the West until, through transgression, the people became apostate and succession in the priesthood no longer obtained. See Book of Mormon, 3 Nephi 11 and later chapters. There is but one church on the earth today claiming authority in the Holy Priesthood by direct succession from the Primitive Church; and surely none can consistently assert priestly powers by spontaneous origination. The rational interpretation of history reveals the literal fulfilment of ancient prophecy in the absolute loss of sacerdotal authority during the early centuries of the Christian Era; so that present-day claim to the Priesthood through unbroken succession from the Apostles of old rests upon arbitrary assertion only. If a mother church be devoid of Divine commission in the Holy Priesthood, definitely and authoritatively vested, no sect springing from that parent institution can inherit the Priesthood.
